I have a flat top AR and an FAL

I am thinking I want an eotech on each but I would like to be able to snap on a night vision scope when needed. Is there a reliable/quick mounting system for me to do this? What would you recomend?

thanks
Bill

Replace the FAL's dust cover with a scope rail cover. I have the one made by DSA and it works well - holds nice and tight without a hint of movement. The AR already has proper rail.

Then you mount a Night Vision Rifle scope on either rail. Zeroing is going to be a problem as each rifle would shoot to a different point of aim with the NVR scope.

I have a NVR scope adjusted for my M1A where I can just unlock the glass scope and replace it with the night vision one in about a minute.
